Sardine Harvest a Threat to Mighty Humpbacks?
Alarms by BC scientists, tour operators don't convince DFO.
Whalers killed the last humpback whale in the Georgia Strait off the mouth of the Fraser River in 1907. Now, the humpbacks are returning to the Strait, and to other BC waters.
But whale researchers and whale watching operators are questioning whether a revival of a different kind -- an expanded fishery for pilchards (Pacific sardines) mandated this year by the DFO -- could threaten the return of the humpbacks.
Both the humpbacks and the pilchards have been observed in increasing abundance along the BC coast in recent years. The humpbacks are a particular boon to the whale watching industry along the coast, as their dramatic breaching behaviour, long, wing-like fins and dramatic "lunge feeding" combine to make the 40-ton leviathans among the most picturesque of the world's whales.
The humpback was hunted to near extinction during the 20th century. Currently, the humpback population of the North Pacific is estimated around ten thousand animals, up from a remnant population of only a thousand whales when whaling stopped in the 1960s.
Many observers link their reappearance along BC's coast to the comeback of pilchard populations over the same time span. Researchers are still investigating the relationship between pilchards and humpback whales, but many believe that the small fish make up an important element in the marine mammals' diet.
Ramped up catch limits
Pilchards, which once sustained a major fishing industry from Mexico to Alaska (and fed the canning industry John Steinbeck portrayed in Cannery Row) had almost disappeared by the end the 20th century, in part because of over-fishing and in part because of poorly understood natural cycles of abundance. At any rate, the pilchards are back in large numbers along our coastline, and the humpbacks seem to have come back with them.
The Department of Fisheries and Oceans has been gradually ramping up a commercial fishery on the increased pilchard stocks since 2002, and for the 2005 season (set to run from July 11 of this year until Feb. 9 of 2006 along the BC coast) the number of boats licensed to fish for pilchard has been doubled from last year's 25 to 50 for this season, with a maximum catch of 17,903 metric tones of fish to be taken.
Dr. Jim Darling, a whale scientist with the Pacific Wildlife Foundation, told The Tyee he is worried that this expanded fishery could drive humpbacks out of BC waters to areas where their food supply is more abundant.
Fears of net entanglements
"There is very limited scientific information available to define the extent of this conflict," Darling said. "However, it is quite clear the behaviour of the humpbacks is tied to the abundance and behavior of the fish. There is not only a potential conflict over the resource, but also, if fishing is allowed amongst the whales, the potential for net entanglements increases -- a significant problem in other parts of the world."
Darling warned that imprudent expansion of the fishery could damage local whale watching, a multi-million dollar eco-friendly business helping to shore up economies of small towns on the outer coast of Vancouver Island.
DFO spokespeople say Darling has nothing to worry about. Sandy McFarlane, a sardine expert with the Department, told The Tyee that the 2005 opening on pilchards, even with twice as many boats on the water, is still a very small fishery. "The size of this fishery would not have any impact on humpback whales," he said.
Lisa Miachika, Pelagic Resource Manager for DFO on the Pacific coast told The Tyee the Department was sure that there was enough pilchard biomass in BC waters to support the proposed fishery.
"We are expanding this fishery very slowly," she said. "We certainly wouldn't say that this represents over-fishing. We don't see any conflict at this time."
Income for sockeye fishermen
Don Pepper, executive director of the Canadian Pacific Sardine Association (an industry umbrella group) is also reassuring on the question of a possible conflict between the pilchard fishery and the continued presence of humpback whales in BC waters.
"We've got more pilchards than the humpbacks could ever eat. I maintain we've got 200 to 300 thousand tonnes in Canadian waters. This is a clean fishery, with hardly any byecatch. We're opening up new markets in China, Russia, Ukraine and Poland, and this will provide some income for fishermen who aren't able to make any money on sockeye," he told The Tyee in a phone interview.
By September 7, according to Miachika, the BC fishery had landed approximately 1.4 thousand metric tonnes of pilchards, with only 9 of the allowable 50 boats so far participating in the fishery. However, she said she expected the number of boats and volumes of fish caught to pick up soon, although she does not expect the entire total allowable catch, set at 17,903 metric tones, to be landed by the end of the season.
'Still endangered'
Other environmentalists and figures within the whale watching industry, however, echoed Jim Darling's concerns, and raised questions about the quality of DFO science and management decisions.
Dr. Paul Spong, whale researcher on the BC coast since 1970 and the director of Orca Lab, a land-based whale research station on Hanson Island at Blackney Pass, told The Tyee that an expansion of the pilchard fishery didn't make sense. "Humpbacks are still endangered," Spong said.
Kati Martini of Remote Passages, a whale watching operation in Tofino, told The Tyee that the arrival of significant numbers of humpbacks in BC waters over the last decade has been great for her industry.
"We're watching humpbacks as often as gray whales now. They're larger than the grays, and more active at the surface, jumping and breaching," she said. "DFO should question the whole idea of an industrial fishery on pilchards. The recovery of these fish is not well understood. We have a challenge getting DFO to see the relationship between the pilchards and the whales."
Whale watching nets millions
Any negative impacts on the whale watching industry caused by a pilchard fishery expansion could have major implications for the economic health of BC's coastal communities, Jamie Bray, owner of Jamie's Whaling Station in Tofino, told The Tyee.
"There's way more money in whale watching than in a few cans of sardines," he said. "The industry brings in over eight million dollars a season on this coast. Spin off effects probably triple that benefit."
Bray said whale watching currently supports close to 30 companies on BC coast.
Marine researcher Alexandra Morton called for studies by experts outside the DFO on the relationship between pilchards and humpbacks in BC, as did Vicky Husband, BC Conservation Chair for Sierra Club Canada. "Pilchards are a critical forage fish," said Husband. "If we want to support the return of the humpbacks, we should move extremely carefully, especially in a time of ocean warming and extreme uncertainty."
Whale biologist Jim Darling says the DFO officials have heard the concerns he and others are voicing. "So far," Darling said, "discussions with DFO have been amiable, with the seeming attitude of 'Let's see if we can define the potential problem and resolve it,' rather than butting heads."

Comments on "Sardine Harvest a Threat to Mighty Humpbacks?&
If ever there was an agency less concerned with sustainability of any kind, the DFO should be first on anyone's list.
Without in any way downplaying potential risk to the Humpback whale, I'd to point out the following to Tyee readers:
As we know, all life begins with the Sun, and on the land, the primary harvesters of that energy are plants. Without them, we would quickly starve.
In the ocean, the primary gatherers of the Sun's energy are the algae in the nearshore, such as Kelp, and in the oceans and seas, the phytoplankton, one-celled plants.
But we cannot harvest phytoplankton, nor several levels up. The smallest we can economically harvest is the Krill, a very small sort of shrimp. All these primary levels of oceanic life are harvested by the so-called "forage fish", such as sardines, herring, anchovies, sandlance, menhaden, and so on, the first "Useful" organisms in the chain for larger animals such as ourselves. If they don't collect this energy, it is lost, except to such as Baleen whales and jellyfish.
But we prefer to forget that we treasure larger predators such as salmon, halibut, various other groundfish, etc. far more, and that all of them are entirely or partly dependant upon the forage fish to harvest the Sun's energy for them just we depend upon the beef which depends upon grass.
But we are vacuuming up the forage fish in all the Worlds oceans. Some stocks, like the North Sea Sandlance, are near extirpation. Without them, how will we, let alone all the other creatures that depend upon them to harvest the Sun's energy from the Phytoplankton, then do so?
The comings and goings of forage fish are little understood, and we know that "Harvest management" is all that DFO will pay for. So then so much for Humpback whales, too.
If you're interested in learning more about the role of forage fish, here's an escellent Discover article about Menhaden - a must read for the informed person.

This, from the article, really disturbs me. I anticipate the same situation that exists with herring. As prices and these exports of the fish increase, the home consumer will be neglected.
It is years since I've seen a fresh herring in a supermarket - or in my local fish store for that matter.
We have a ridiculous situation where a radio station appears to have a monopoly on the sale of fresh herring to the Canadian public. Invariably this sale occurs bi-annually in New Westminster.
The price is right but, in the lining-up waiting to fill your bucket, you may expire from hypothermia, as I almost did on one occasion.
I would like to hear from a commercial fisher the rationale behind this selling method.

As I recall, Skep, after WW2, the large overseas food sardine market (primarily Japan) we had prior to the War disappeared.
The industry then became entirely a "reduction fishery" in which the fish became fertiliser or mink food. The herring were grossly overharvested and the fishery collapsed.
Today the fish are harvested for the roe, with the carcass becoming food for fish farms.
Stocks are managed just above the numbers required for a bit of comfort, reproduction and a small harvest.
There is a bait herring fishery in the Gulf of Georgia, so perhaps you could buy some fish bait to eat!!!!
The Haida have banned a kill fishery for herring in the waters around the Charlottes, and instead focus upon roe-on-kelp, (Ghow or K'aaw), the only logical way to sustainably harvest herring.

Finally got to the link mentioned in scylla's first posting.
A wonderfully written article and an easy read with the large print.
excerpt:
Not one of these fish is destined for a supermarket, canning factory, or restaurant. Menhaden are oily and foul and packed with tiny bones. No one eats them. Yet they are the most important fish caught along the Atlantic and Gulf coasts, exceeding the tonnage of all other species combined.
I wonder if this fish goes under another name.
I'd like to take the challenge and, just as I do with smelt, pan-fry a few and slap them between two slices of toast with a little mustard - yummee!
Seriously, it's a global problem with a domino effect potentially damaging many species and calling for a cooperative, world body to apply solutions.
The alternative is to stand by as an industry driven by greed and ignorance, and that seems bent on suicide, reaches that point of no return.

Okay, perhaps my question re: these fish going under a different name was silly, but the threatened menhaden were not mentioned in the introductory article and I was thrown by the "oily and foul" in the quote from the link.
I believe that for marketing purposes fish are occasionally renamed. Perhaps what the English call the sprat, turbot, whiting, or plaice are named differently in Canada.
I'm not sure of its veracity but believe the story to be true: that even though a ban was put on dogfish sale for local consumption because of high mercury content, the fish were still being exported to Europe where it would be sold under a different name.

Skep, Simce I had lost the site address for the Discover article, I Googled Menhaden, and was surprised to find how many sites there are now extolling the culinary delights to be found in the lowly Menhaden.
My guess is there is a similarity there to our new-found appreciation for Pink salmon, for I'm old enough to remember when local people would never, ever, admit to actually eating such a "junk fish".
Just another example of scarcity pushing humans ever lower down the food chain, eh? I expect that soon we'll be told of the delights found in eating "Mud shark" (Dogfish), and DFO will begin "managing" that one for us too.

Skep,
I'm unaware of the mercury-in-Dogfish issue. Perhaps that's why we hear so little about that fishery these days. As far as I know, that issue mercury hasn't hurt the Tuna fishery.
But my contrarian-oriented thinking insists on crying "foul" here, prompted by your pushing me to research Pasteurisation, etc, re our byplay discussion about milk on the Cycling thread.
So, of course, I then find some very disturbing info re these processes, which I am inclined to believe at least in part, echoing your cautioning re "marketing purposes". Among such marketers are enviros who have massaged the businessman's "bottom line" dictum to now read "the end justifies the means" (lying to the public is OK if it's for their own good).
I pity the bureaucrat charged with regulating who is torn between business-oriented info and equally contrived info from enviros - both of which are not above seeking and thus adding "spin".
And what about any respect for the public?? In my little town, where the tap water is already as naturally pure as can be had, people are paying for bottled water at a price above that of gasoline, because it isn't chlorinated. And despite all the possible side effects of doing so, not a word from our health-conscious enviros.

Following your lead, scylla, I Googled: fish sprat It took me to a colorful and informative, Norwegian species guide.
More and more it seems that sardine is a generic term covering several species. I must say, the sprat is a handsome little fish.
excerpt;
Use
Sprat is an important raw material for the canning industry, where it is marketed as sardines and anchovies. Sprat is also an important industrial fish. Fresh sprat is delicious fried or grilled.
Nutritional value:
Sprat is an excellent source of omega-3 fatty acids and vitamin D. It also has a high content of vitamin B12. Eating a small amount of sprat as a garnish or on bread (25 g) provides a valuable dietary contribution.

And the Atlantic Turbot is marketed as Greenland Halibut.
And turning to dry land, HR MacMillan got his business start by marketing previously unsaleable Hemlock lumber in Europe as "Northern Fir".
Whoops - we've gone a long way from Humpback whales and Pacific sardines.
I find it utterly amazing, given all the experience we've had with fishermen's greed and DFO's overreadiness to assuage it, our astute(?) politicians have allowed them to attack these new stocks - which many years back were enormous - before they know how large the stocks could grow to; how large the stock biomass has to be in, to be able to protect its niche; or what impacts the Pacific sardine has on the trophic levels above and below it.
Here we have the recovery of a stock we nearly extirpated, and these greedy turkeys just can't stand seeing all that free money going to "waste".
In my opinion, the greediest logger is a pussycat compared to the commercial fisherman.

The ominous side to all this is that the present abundance of Sardines is widely thought to be caused by warmer water.
A few years back there was a huge Sardine 'die off' near Port Hardy which FOC attributed to colder water coming in from the N. Pacific.
Some NCVI beaches were covered with windrows of dead Sardines.

Sam, the Japanese Current has wandered on and off the Northeast Pacific (our) Coast for untold time.
Examples of this are the Turtles, Sunfish, White sharks, etc, which come in with fingers from this warm-water current, which get cut off, then cool, causing the cold-intolerant creatures to die.
Nobody knows for sure if the present phenomenon is just a larger one of those events, or whether it is a symptom of Global Warming.
Which sent me off Googling again, and coming up with this very interesting article, written before today's return of the "pilchard". http://www.portaec.net/library/ocean/disappearance_and_return_of_the.html
A quibble and an observation re the article though. As far as I know, the Portuguese Man o War is a rare if ever, visitor to our shores. More likely the jellies were Vellela, a much smaller look-alike.
Which prompts an amusing story told to me by a native elder many years ago. Though not at all dangerous, Vellela does have "stingers". The men of his village would gather them when they washed up in large numbers`on the beach. Then when a dance happened, the dried and powdered jellies were sprinkled on the floor, and during the dance the dust would waft up the ladies skirts. He's long gone now, but I can still hear his laughter.
On a more serious note, as the Discover article noted, jellyfish are direct competitors with forage fish and their presence in large numbers can indicate something's wrong at that trophic level. That occurrence is prompting concern in what became a "goldrush fishery" in the Bering Sea.
Another sidebar to that story is that I read in the Hational Fisherman some years back that a West Coast fisherman had discovered a small run of Pacific sardine in the Nitinaht Triangle, Whereupon DFO immediately granted him a quota on the grounds that the run was an anomaly, probably overflow from the recovering Californian fishery.
If anyone wonders why I hold such a distaste for DFO, it's because it is money and politics that fuels that evil organisation, not Science.

I'm sure you have us all on tenterhooks, scylla.
To what effect? Cayenne pepper-like? Aphrodisiac? Perhaps a little of both. That would be interesting.
I'm assuming that the jellyfish were gathered for other reasons - food for instance.
I believe N. Americans tend to be quite elitist in their fish eating. And this has undoubtedly hurt the industry by too much concentration on particular species.
I notice in the Asian markets much larger variety of seafoods including what-appear-to-be sun-dried minnow-like fish, shrimp and seaweeds.

I, too, question the whole whale watching thing and prefer that they be viewed from a TV or large screen.
I don't doubt that some of these tour operators feel they have to squeeze something (anything) in between visiting casinos, so that they don't appear just as shills for the gambling industry.
I can't believe boats in constant proximity to the whales - especially those with calves - is any benefit to the animals - and is probably harmful.

Yeah, skep, I saw that as soon as it was posted, composed a clarification, then changed my mind as it might be seen as condescending.
The dust created an itch, the remedy for which you can easily guess :-]
I doubt very much the dust created any harm, or that the ladies were totally unaware - or unforgiving - of the joke being played on them.
As far as I know, there is insufficient food value in jellyfish to warrant collecting them, even in desperate times. I read once of the Japanese making a sprciality item out of one particular species.
We've seen pictures of poor Asian fishermen casting mist nets in shallow water for very small fishes. At first I was shocked because I knew many large fish begin life as "minnows" in intertidal waters. "How Stupid" I thought, and then realised if they didn't do so, they and their families would starve.
And so, I can relate to the readiness with which many immigrant Asians fish for undersized local stocks. It's hard to chuck an ethic you've held most of your life. Caucasian hunters, loggers, etc, are facing similar "culture shock" as the hard realities begin to pile up before their unseeing eyes.
Similarly, many Canadian Aboriginals hide behind the excuse that "it is all the white man's fault" and therefore the reality and the rules it creates should not apply to them.
In Dark Ages Ahead, Jane Jacobs writes: "in the end, even the memory of what is lost, is lost".

Skep and Sam, while I can easily relate to your observations re the potential effects upon the whales from the whale-watching "industry", I take this somewhat hard-hearted position, akin to the way I feel about zoos.
We are indeed "users" of natural resources (horrible term). Pointing out that inescapable fact, the industrial "wise users" see such activities as "Disney-izing" wildlife, while the purists evoke quasi-spiritual reasoning to prove we should not be using them at all.
In my mind, Disney-izing is a first step in creating a humane ethic re our treatment of animals, especially among those cement-bound new generations who are unlikely to see a wild animal unless it's in a documentary or in a fleeting glimpse from a car window.
Those who are really concerned for animal welfare (and the effect present attitudes have on our own collective psyche) should first address factory-farming, a form of disgusting brutality few of us want to comprehend.
In my experience, wild animals quickly adjust to the presebce of humans, once they percieve there there is no threat intended. Thus, if the watchers are taught they must resist the temptation to invade the animal's "space", a huge lesson is imparted.
The way is then paved to raising public awareness re addressing a formidable problem - the accelerating degradation of the Continental near and offshore waters from agricultural, industrial, and urban waste.
There's no easy answers to our cooexistence with wild animals though. What do we do with the rapidly-growing flocks of geese which adjust to urban living, destroying farmer's crops, pillaging zoo gardens and making golf courses unplayable? Or the coyote in Vancouver intent upon gobbling up poochies and pussycats?

On the matter of the golf courses, I'm on the side of the defecating geese. Golfers should consider it just another hazard to play around or through. With all those birds killed or made barren with the weeding and feeding those geese, unable to raise a middle digit, are giving a message the best way they know how.
On the matter of squid, they at least are edible - though it's probably not a good idea to use those dead on the beach for food.
Some may also have qualms about eating a "highly intelligent" animal. It must be that intelligence that enables them to catch the salmon given the salmon's - I would think - superior speed. Perhaps the squid are going after sick stragglers.
On rare occasion I've bought small squid at my local supermarket and quite enjoyed them. At a local Asian food court breaded squid may be had. They appear to be the tentacles from larger squid. I've tried them a couple of times and found them quite palatable but a little bland and rubbery - possibly under-cooked.

Does anyone know if Northern Right Whales eat pilchards? They are the most endangered cetacean, only sighted 12 or 13 times since the ban on whaling.
“Everyone agrees it’s a desperate situation, but the tendency is to complain rather than bite the bullet and do something substantive about it. The sea is a commons, and everyone is looking out for their own self-interest. In the simplest terms, the fight is over who will catch the last fish rather than husbanding and restoring the fisheries.â€
